At first blush, I think the Michael J. Fox ads on stem cell research scare people on the right. Here we have an actor who is very well liked and sympathetic in his plight making a call for political help.
Don't worry. I'm pretty sure this is going to end up helping the GOP quite a bit. Two related reasons:
1. The Democrats have so far succeeded by existing almost entirely as a protest to the Iraq war which has been costly and semi- (dare I say it?) quagmire-ish. Putting the stem cell issue out on the table is a stupid diversion from a good strategy. Instead of "We're not Bush," they are now saying, "And we want to start pushing the envelope on bio-ethical issues just like we have been on questions of sex."
It's a big reminder of the life issue and whether you believe it or not, that one is becoming a big loser for the left. Pro-life will eventually be what anti-racism became.
